Compare granite with marble stone
Granite is a light-colored igneous rock with grains large enough to be visible with the unaided eye. It forms from the slow crystallization of magma below Earth’s surface.
Granite is used for flooring and commercial purposes because of its firmness, high dimensional stability and excellent vibration physiognomies. The stone not only lays the foundations of a house but also gives it a look perfect for modern architecture. Being a natural source of radiation, there is no decay factor attached to the stone.
Benefits of Granite Stone
- Granite has low water absorption, hence it is used in wet areas and in areas of exposed water, including baths, toilets and kitchens.
- Granite stone has an intrinsic property against pollution and dust.
- Its resistance to acid and chemical substances is high and its color is not dimmed due to these factors.
- This stone cannot easily be scratched.
- Granite stone consists of a variety of crystals, so it is found with beautiful texture in nature.
- Granite resistance is high to heat and fire.
- Variety of colors of Granite stone is high and is available in black, pink, orange, blue, green and brown.
- Granite stone is used in various parts of the building, wall covering, flooring, and kitchen countertops and so on.
- Its durability and longevity make it an ideal stone for construction purposes.
- There are a lot of mines in Iran to extract this rock.
Disadvantages of Granite Stone
One of the disadvantages of granite rocks is emitting radioactive waves. If these stones are located in places where gamma radiation, x-rays, magnetic waves or strong chemicals are present, it will reflect these waves and lead to dangerous diseases such as cancer in humans. Therefore, the stone is not used in such places.
Granite or marble which is better
In geology, the term “marble” refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. A related rock, dolomitic marble, is produced when dolostone is subjected to heat and pressure.
Marble is a classic architectural material and is suitable for a variety of applications from countertops to building facades.
Benefits of marble Stone
Marble as natural stone is the most elegant and luxurious stone. It is also highly versatile as it can be used in flooring, ornamental furnishings, fireplace and bathrooms. Marble is very beautiful and comes in a variety of colors ranging from milky white to red and black which is the result of impurities present in the stone’s structure. The impurities are in bands which increase the elegance of the stone. However, since marble is made of calcite crystals which is a salt of calcium, marble is prone to staining especially from liquids which are acidic in nature due to which it is usually not recommended to install marble for exposed places like commercial kitchens.
Compare marble with granite
The appearances of both marble and granite is quite different from each other. Granite’s color variation appears as freckling throughout the stone because granite has meddled stones in it like feldspar, mica and amphibole. Marble has a grayish or cream color with veins running through it. The veins in marble are usually due to impurities like iron oxide.
Hardness and longevity:
Granite is harder and stronger than marble. It is mostly known as the most durable natural stone and compared to marble. It is resistant to heat and can easily withstand hot cookware therefore it is perfect for kitchen tops. Marble is also susceptible to fading of color and becoming duller overtime. Unlike the stains which can be removed, a dulled marble has no way getting its shine back. It is an irreversible process and a major drawback of marble.
Reactivity to Acidic substance:
Both natural stones have a porous structure but the metamorphic attributes of marble makes it more porous and therefore marble is easily stained from spills especially from liquids that are acidic in nature like fruit juices and wines. Granite is much more resilient towards stains as long as an effective sealant is maintained on the surface liquid spills will not permeate into the surface.
The actual price however depends on the quality of the stone, complexity of the job and the style of the tiles. Granite and marble both are to be installed by professionals as the slabs are really heavy. Granite is cheaper than its counterpart marble.
Applications with them:
The durable quality of granite makes it appropriate for kitchen countertops and hallways where there is high foot activity. Marble is more apt for areas where there is less traffic like bathrooms. Marble gives a bright unique look and is suitable for surfaces that are used less frequently.
To prevent staining and etching, Sealants are used on both granite and marble. Marble requires sealing much more frequently twice a year and granite sealing once every two years is sufficient. The actual requirement for resealing depends on how heavily the surface was used and how regularly the stone’s cleaning was done.
